The Superiority of European Triple Glazing: An In-depth Comparison with American Standards

Triple-glazed windows have become synonymous with energy efficiency, offering unrivaled insulation compared to their double-glazed counterparts. But not all triple-glazed windows are created equal. In this post, we’ll explore the fundamental differences between American and European triple glazing, focusing on the exceptional performance of Internorm’s products.

Understanding Triple Glazing

Triple-glazed windows consist of three layers of glass with insulating gas-filled spaces in between. These windows dramatically reduce heat loss, enhance sound insulation, and minimize condensation. Their effectiveness is often measured using the U-value, which indicates the rate of heat transfer – lower U-values signify superior insulation1.

European vs. American Triple Glazing: A Comparative Analysis

While both American and European triple glazing aim to improve energy efficiency, there are stark differences in their construction and performance.

Insulating Glass Units (IGUs)

The thickness of the Insulating Glass Units (IGUs) differentiates European and American triple glazing. European manufacturers like Internorm use 48mm IGUs, while American triple glazing typically features IGUs up to 36mm2. The additional thickness in European IGUs allows for larger gas-filled spaces, resulting in better insulation.

U-Values

The construction and IGU thickness differences result in varying U-values between European and American triple-glazed windows. Internorm’s triple-glazed windows achieve Uw values as low as 0.60 W/(m2K), significantly outperforming many American triple-glazed windows3.

Glass Thickness

Internorm uses three 4mm thick glass panes in their triple-glazed windows4, whereas many American manufacturers use thinner glass layers. The thicker glass heightens sound insulation and durability, contributing to the overall window performance.

The Internorm Advantage: Unmatched Performance and Efficiency

Internorm’s triple-glazed windows stand out in the global market due to their superior construction and exceptional performance. Here’s why:

  • Superior Insulation: With 48mm IGUs and Uw values as low as 0.60 W/(m2K), Internorm’s triple-glazed windows offer unparalleled insulation, reducing energy costs and enhancing indoor comfort5.
  • Enhanced Durability: The use of thicker glass panes not only improves sound insulation but also enhances the durability of Internorm’s windows, offering homeowners a long-lasting solution.
  • Optimized Energy Efficiency: By reducing heat loss and harnessing solar gain, Internorm’s triple-glazed windows contribute to the overall energy efficiency of a home, aligning perfectly with sustainable living goals.

Conclusion

While both American and European manufacturers offer triple-glazed windows, the superiority of European models, particularly those from Internorm, is clear. With their thicker IGUs, lower U-values, and robust construction, Internorm’s triple-glazed windows offer an unmatched combination of energy efficiency, durability, and comfort – making them the ideal choice for homeowners seeking the ultimate in high-performance windows.
